Cell webquest

Go to this site: http://www.biologyjunction.com/cell_exploration_webquest.htm
Complete the activity. Create a word document or hand write, etc. your answers and data table.

Homeostasis lab

Background:
Exercise causes many factors of homeostasis to kick in to maintain internal equilibrium. How exercise affects some of these factors can be determined by measuring and observing certain conditions of the human body. Brainstorm some of these conditions in your group.


Activity:
1. Devise an experiment that will test the effects of exercise on homeostasis.
2. Before beginning, decide what you will look for in the various conditions you identified above.
3. Exercise should be sustained for at least 8 minutes. Determine when and how you will collect data.
4. Create a data table and graph.
5. Create a conclusion.

Analysis:
1. What are the changes that you observed throughout the experiment?
2. How do each of those changes help the body adjust to maintain equilibrium (homeostasis)?
3. What mechanisms are used to maintain body temperature in the body?
4. What is the purpose for an increased respiratory rate and heart rate?
5. Write a paragraph about the conclusions you can draw about your body's ability to maintain equilibrium (homeostasis.) Be sure to discuss some of the information from your other answers.

Cell parts review

Complete the following document to review the cell parts:

Cell transport

View the different molecules and their passage through: http://www.teachersdomain.org/asset/tdc02_int_membraneweb/

Click on each of the molecules and watch as they move in and/or out of the cell. Note that the inside of the cell is the right side of the screen and the outside of the cell is the left side of the screen. Write down the direction that each of the particles move and how they move across (what part of the cell membrane they move through.)

Diffusion and osmosis

Complete the following document. Use the links and answer all questions completely.
